Jquery function to Dom7 function

Questions
1

I have the following jquery function in a project and would like to convert it to Dom7. If this succeeds, jquerry would be redundant in the project.

Unfortunately I do not succeed, can someone please help me with this?

$(stage).animate({
  "top": "+800px"
}, "fast", function() {
  finalquestion = false;
});

What is your ‘stage’ object?

3

Stage is a div containing a content block.

Have you declared access to it in a different method than a standard ID or class selector? The reason I ask is you have $(stage) with no selector, a better usage would be:
$('.stage').animate // (for class='stage')

$('#stage').animate // (for ID='stage')

5

My HTML looks like:
<div id="stage">...</div>

var $ = Dom7;
$('#stage').animate({
  "top": "+800px"
}, "fast", function() {
  finalquestion = false;
});

The use of ‘$’ relies on not having jQuery in your project. If you are also using jQuery alongside F7, change $ to $$

var $$ = Dom7;

And then use $$. as the reference.

jquery is obsolete (years ago)
you should not use it anyway

here is the syntax of Dom7.animate:

$('#stage').animate({
  'attr': 'value'
},{ complete: () => console.log('completed') });
